M-PESA C2B INTEGRATION ๐ Most devs integrate M-Pesaโฆ but ignore security + real-world edge cases ๐จ Over the past week, I built a production-ready Customer To Business (C2B) confirmation handler for a client and hereโs the realityโฆ Itโs not just "receive payment and update balance." HOW IT WORKS - Customer pays Paybill - System validates the request - Transaction is verified - User account is credited instantly Sounds simpleโฆ until you handle what can go wrong ๐ - Only Safaricom requests allowed (IP whitelisting) - Duplicate transactions blocked (idempotency) - Phone numbers normalized (254 / 07 / 7/ 01/ 1 formats) - Every request logged for audits (Audit Logging) - Deposits processed safely and consistently (Transactional integrity) This is the difference between a Just working and a real production-ready system. Most integrations fail in production because they skip this layer. If you are building with Safaricom M-Pesa or any fintech API? Letโs build it right ๐
